摘要： A liquid ejecting head includes a flow channel forming substrate having pressure generation chambers communicating with a nozzle opening and arranged in parallel along a lateral direction. A piezoelectric element is provided on one surface of the flow channel forming substrate in correspondence to the pressure generation chamber, and has a first electrode, a piezoelectric layer provided on the first electrode and a second electrode provided on the piezoelectric layer. In a direction intersecting with the arrangement direction of the pressure generation chambers, in boundaries between an active section that is a substantial driving section and an inactive section that is not a substantial driving section of the piezoelectric layer, the first electrode includes a taper section of which a width is gradually decreased toward the boundary from the active section side.

摘要： A liquid ejecting head has a piezoelectric element with a first electrode, a piezoelectric layer, and a second electrode. The liquid ejecting head causes pressure changes in a pressure generating chamber communicating with a nozzle opening. The piezoelectric layer has a perovskite structure and is preferentially orientated in a (100) plane. A method for producing the liquid ejecting head includes polarizing the piezoelectric layer by applying an electric field having energy higher than energy required for converting the polarization direction in the direction to the direction and lower than energy required for converting the polarization direction in the direction to the direction when the electric field to be applied to the piezoelectric layer is in the direction vertical to a plane on which the second electrode is provided.

摘要： A method of manufacturing a potassium niobate (KNbO3) single crystal thin film, includes the steps of maintaining the substrate under a predetermined oxygen partial pressure; maintaining the substrate within a temperature region which is equal to or higher than an eutectic temperature of KNbO3 and 3K2O.Nb2O5 and is equal to or lower than complete melting temperature of KNbO3 and 3K2O.Nb2O5 so that a solid phase of KNbO3 and a liquid phase can coexist on the substrate; depositing a vapor phase material on the substrate in a state in which a solid phase and a liquid phase coexist; and precipitating KNbO3 on the substrate from the liquid phase as a solid phase to grow a KNbO3 single crystal thin film. The composition of a starting material to be vaporized to generate the vapor phase material is from K2O.Nb2O5=50:50 to K2O.Nb2O5=65:35.
